Magnetization relaxation and search for the magnetic gap in bulk-insulating V-doped (Bi, Sb)Te
E. Golias, E. Weschke, T. Flanagan +9
V-doped (Bi,Sb)Te has a ten times higher magnetic coercivity than its Cr-doped counterpart and therefore is believed to be a superior system for the quantum anomalous Hall…
Helicity dependent photocurrent in electrically gated (Bi,Sb)_2Te_3 thin films
Yu Pan, Qing-Ze Wang, Andrew L. Yeats +7
Circularly polarized photons are known to generate a directional helicity-dependent photocurrent in three-dimensional topological insulators at room temperature. Surprisingly, the…
Ferromagnetism and Spin-dependent Transport in n-type Mn-Bi2Te3 Thin Films
Joon Sue Lee, Anthony Richardella, David W. Rench +5
We describe a detailed study of the structural, magnetic, and magneto-transport properties of single-crystal, n-type, Mn-doped Bi2Te3 thin films grown by molecular beam epitaxy. Wi…
Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator
Duming Zhang, Anthony Richardella, David W. Rench +12
The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…
